WebAug 1, 2001 · Both coniferyl and sinapyl alcohols, as well as coniferyl and sinapyl aldehyde, are substrates of a xylem cell wall-located strongly basic peroxidase, which is capable of oxidizing them in the absence and in the presence of hydrogen peroxide. WebJun 7, 2024 · Coniferyl aldehyde may also be hydroxylated by the action of coniferyl aldehyde 5-hydroxylase (CAld5H; EC 1.14.13.-) and, then, methoxylated in C5 by COMT to form sinapyl aldehyde. Sinapyl alcohol dehydrogenase (SAD), an enzyme analogous to CAD, reduces sinapyl aldehyde to sinapyl alcohol, the second most abundant monolignol.
